It was a difficult decision but we will not be offering Dan Blakeslee prints or apparel for the 2022 race. We have not sold enough in previous years and the prints were not as popular as hoped, so we will be holding off for a year or two until we find gear that we would like to offer. However, we have a limited supply of swag from previous available for purchase within registration. To view what each item looks like, please click the links below. Some quantities are very limited so don't wait because once they're gone, that's it.

BIB PICKUP (and other items)

  • Friday, April 22nd at Runner's Alley in downtown Portsmouth - from 3pm - 6pm.

  • Saturday, April 23rd near the race start line, from 7:30am - 9:15am

Highlights of this race include running over 4 bridges, and the stunning views, including the Portsmouth Shipyard, the shuttered naval prison, the Piscataqua River, lobster boats, sailboats, the lighthouse, and the Wentworth by the Sea Hotel and Marina. With all of the friendly faces, this race is sure to be one of your favorites.

    This race is LIMITED TO 550 RUNNERS, so reserve your spot now!


  • We're working our hardest to keep this event as environmentally friendly as possible. With that said, some of our steps towards a zero impacting event include:

    • This is a NO PLASTIC BOTTLE event! Instead of providing plastic bottles for everyone as they cross the finish line, we will be providing finishers with a compostable cup to fill with water and then dispose of into a compostable trash bag.​

    • Water stops will be providing water to runners in compostable cups, and then disposing of into a compostable trash bag.

    • This is a carry-in, carry-out event! We only have 1 trash barrel at the event with the goal to NOT fill it; we barely filled it in 2018 and 2019. Plus, in 2020 we didn't add anything to it (but we were virtual, ha)!


  • There is parking at the event, however, while we didn't have any problems fitting everyone in previous years, it's important to know there are a limited amount of spaces. Don't stress about it - we'll make it work, but we need to work together. Please review the tips below to help avoid any problems.

  • Tips to ensure there will be parking for everyone:

    • Please follow the guidance of the amazing volunteers when entering the Great Island Common

    • Carpool​ if you can (most runners carpooled in previous years - THANK YOU)

    • Ride your bike if you're local

    • Spend the night on the lawn

    • Swim in from the Isle of Shoals

    • NO parking on the road outside of the Great Island Common or in the library parking lot (please, we don't want to possibly impact the residents or guests; but just in case - there will be signs)
